I'm using a UIPanGestureRecognizer to recognize horizontal sliding in a UITableView (on a cell to be precise, though it is added to the table itself). However, this gesture recognizer obviously steals the touches from the table. I already got the pangesturerecognizer to recognize horizontal sliding and then snap to that; but if the user starts by sliding vertical, it should pass all events from that touch to the tableview.
One thing i have tried was disabling the recognizer, but then it wouldn't scroll untill the next touch event. So i'd need it to pass the event right away then.
Another thing i tried was making it scroll myself, but then you will miss the persistent speed after stopping the touch.
Heres some code:
//In the viewdidload method
UIPanGestureRecognizer *slideRecognizer = [[UIPanGestureRecognizer alloc]initWithTarget:self action:@selector(sliding:)];
[myTable addGestureRecognizer:slideRecognizer];
-(void)sliding:(UIPanGestureRecognizer *)recognizer
{
if (recognizer.state == UIGestureRecognizerStateBegan)
{
CGPoint translation = [recognizer translationInView:favoritesTable];
if (sqrt(translation.x*translation.x)/sqrt(translation.y*translation.y)>1) {
horizontalScrolling = YES; //BOOL declared in the header file
NSLog(@"horizontal");
//And some code to determine what cell is being scrolled:
CGPoint slideLocation = [recognizer locationInView:myTable];
slidingCell = [myTable indexPathForRowAtPoint:slideLocation];
if (slidingCell.row == 0) {
slidingCell = nil;
}
}
else
{
NSLog(@"cancel");
}
if (recognizer.state == UIGestureRecognizerStateEnded || recognizer.state == UIGestureRecognizerStateCancelled)
{
horizontalScrolling = NO;
}
if (horizontalScrolling)
{
//Perform some code
}
else
{
//Maybe pass the touch from here; It's panning vertically
}
}
